Yet another Internet-connected door lock is insecure:
Sold by retailers including Amazon, Walmart, and Home Depot, U-Tec's $139.99 UltraLoq is marketed as a "secure and versatile smart deadbolt that offers keyless entry via your Bluetooth-enabled smartphone and code."
Users can share temporary codes and 'Ekeys' to friends and guests for scheduled access, but according to Tripwire researcher Craig Young, a hacker able to sniff out the device's MAC address can help themselves to an access key, too.
UltraLoq eventually fixed the vulnerabilities, but not in a way that should give you any confidence that they know what they're doing.
The propagandists have created and disseminated disinformation since at least March 2017, with a focus on undermining NATO and the US troops in Poland and the Baltics; they've posted fake content on everything from social media to pro-Russian news websites. In some cases, FireEye says, Ghostwriter has deployed a bolder tactic: hacking the content management systems of news websites to post their own stories. They then disseminate their literal fake news with spoofed emails, social media, and even op-eds the propagandists write on other sites that accept user-generated content.
That hacking campaign, targeting media sites from Poland to Lithuania, has spread false stories about US military aggression, NATO soldiers spreading coronavirus, NATO planning a full-on invasion of Belarus, and more.
This hack targets the firmware on modern power supplies. (Yes, power supplies are also computers.)
Normally, when a phone is connected to a power brick with support for fast charging, the phone and the power adapter communicate with each other to determine the proper amount of electricity that can be sent to the phone without damaging the device -- the more juice the power adapter can send, the faster it can charge the phone.
However, by hacking the fast charging firmware built into a power adapter, Xuanwu Labs demonstrated that bad actors could potentially manipulate the power brick into sending more electricity than a phone can handle, thereby overheating the phone, melting internal components, or as Xuanwu Labs discovered, setting the device on fire.
Twitter was hacked this week. Not a few people's Twitter accounts, but all of Twitter. Someone compromised the entire Twitter network, probably by stealing the log-in credentials of one of Twitter's system administrators. Those are the people trusted to ensure that Twitter functions smoothly.
The hacker used that access to send tweets from a variety of popular and trusted accounts, including those of Joe Biden, Bill Gates, and Elon Musk, as part of a mundane scam -- stealing bitcoin -- but it's easy to envision more nefarious scenarios. Imagine a government using this sort of attack against another government, coordinating a series of fake tweets from hundreds of politicians and other public figures the day before a major election, to affect the outcome. Or to escalate an international dispute. Done well, it would be devastating.
Whether the hackers had access to Twitter direct messages is not known. These DMs are not end-to-end encrypted, meaning that they are unencrypted inside Twitter's network and could have been available to the hackers. Those messages -- between world leaders, industry CEOs, reporters and their sources, heath organizations -- are much more valuable than bitcoin. (If I were a national-intelligence agency, I might even use a bitcoin scam to mask my real intelligence-gathering purpose.) Back in 2018, Twitter said it was exploring encrypting those messages, but it hasn't yet.
Internet communications platforms -- such as Facebook, Twitter, and YouTube -- are crucial in today's society. They're how we communicate with one another. They're how our elected leaders communicate with us. They are essential infrastructure. Yet they are run by for-profit companies with little government oversight. This is simply no longer sustainable. Twitter and companies like it are essential to our national dialogue, to our economy, and to our democracy. We need to start treating them that way, and that means both requiring them to do a better job on security and breaking them up.
This kind of attack is known as a "class break." Class breaks are endemic to computerized systems, and they're not something that we as users can defend against with better personal security. It didn't matter whether individual accounts had a complicated and hard-to-remember password, or two-factor authentication. It didn't matter whether the accounts were normally accessed via a Mac or a PC. There was literally nothing any user could do to protect against it.
Class breaks are security vulnerabilities that break not just one system, but an entire class of systems. They might exploit a vulnerability in a particular operating system that allows an attacker to take remote control of every computer that runs on that system's software. Or a vulnerability in internet-enabled digital video recorders and webcams that allows an attacker to recruit those devices into a massive botnet. Or a single vulnerability in the Twitter network that allows an attacker to take over every account.
For Twitter users, this attack was a double whammy. Many people rely on Twitter's authentication systems to know that someone who purports to be a certain celebrity, politician, or journalist is really that person. When those accounts were hijacked, trust in that system took a beating. And then, after the attack was discovered and Twitter temporarily shut down all verified accounts, the public lost a vital source of information.
There are many security technologies companies like Twitter can implement to better protect themselves and their users; that's not the issue. The problem is economic, and fixing it requires doing two things. One is regulating these companies, and requiring them to spend more money on security. The second is reducing their monopoly power.
The security regulations for banks are complex and detailed. If a low-level banking employee were caught messing around with people's accounts, or if she mistakenly gave her log-in credentials to someone else, the bank would be severely fined. Depending on the details of the incident, senior banking executives could be held personally liable. The threat of these actions helps keep our money safe. Yes, it costs banks money; sometimes it severely cuts into their profits. But the banks have no choice.
The opposite is true for these tech giants. They get to decide what level of security you have on your accounts, and you have no say in the matter. If you are offered security and privacy options, it's because they decided you can have them. There is no regulation. There is no accountability. There isn't even any transparency. Do you know how secure your data is on Facebook, or in Apple's iCloud, or anywhere? You don't. No one except those companies do. Yet they're crucial to the country's national security. And they're the rare consumer product or service allowed to operate without significant government oversight.
For example, President Donald Trump's Twitter account wasn't hacked as Joe Biden's was, because that account has "special protections," the details of which we don't know. We also don't know what other world leaders have those protections, or the decision process surrounding who gets them. Are they manual? Can they scale? Can all verified accounts have them? Your guess is as good as mine.
In addition to security measures, the other solution is to break up the tech monopolies. Companies like Facebook and Twitter have so much power because they are so large, and they face no real competition. This is a national-security risk as well as a personal-security risk. Were there 100 different Twitter-like companies, and enough compatibility so that all their feeds could merge into one interface, this attack wouldn't have been such a big deal. More important, the risk of a similar but more politically targeted attack wouldn't be so great. If there were competition, different platforms would offer different security options, as well as different posting rules, different authentication guidelines -- different everything. Competition is how our economy works; it's how we spur innovation. Monopolies have more power to do what they want in the quest for profits, even if it harms people along the way.
Maybe this hack will serve as a wake-up call. But if past incidents involving Twitter and other companies are any indication, it won't. Underspending on security, and letting society pay the eventual price, is far more profitable. I don't blame the tech companies. Their corporate mandate is to make as much money as is legally possible. Fixing this requires changes in the law, not changes in the hearts of the company's leaders.
A criminal group called Cosmic Lynx seems to be based in Russia:
Dubbed Cosmic Lynx, the group has carried out more than 200 BEC campaigns since July 2019, according to researchers from the email security firm Agari, particularly targeting senior executives at large organizations and corporations in 46 countries. Cosmic Lynx specializes in topical, tailored scams related to mergers and acquisitions; the group typically requests hundreds of thousands or even millions of dollars as part of its hustles.
For example, rather than use free accounts, Cosmic Lynx will register strategic domain names for each BEC campaign to create more convincing email accounts. And the group knows how to shield these domains so they're harder to trace to the true owner. Cosmic Lynx also has a strong understanding of the email authentication protocol DMARC and does reconnaissance to assess its targets' specific system DMARC policies to most effectively circumvent them.
Cosmic Lynx also drafts unusually clean and credible-looking messages to deceive targets. The group will find a company that is about to complete an acquisition and contact one of its top executives posing as the CEO of the organization being bought. This phony CEO will then involve "external legal counsel" to facilitate the necessary payments. This is where Cosmic Lynx adds a second persona to give the process an air of legitimacy, typically impersonating a real lawyer from a well-regarded law firm in the United Kingdom. The fake lawyer will email the same executive that the "CEO" wrote to, often in a new email thread, and share logistics about completing the transaction. Unlike most BEC campaigns, in which the messages often have grammatical mistakes or awkward wording, Cosmic Lynx messages are almost always clean.
French police hacked EncroChat secure phones, which are widely used by criminals:
Encrochat's phones are essentially modified Android devices, with some models using the "BQ Aquaris X2," an Android handset released in 2018 by a Spanish electronics company, according to the leaked documents. Encrochat took the base unit, installed its own encrypted messaging programs which route messages through the firm's own servers, and even physically removed the GPS, camera, and microphone functionality from the phone. Encrochat's phones also had a feature that would quickly wipe the device if the user entered a PIN, and ran two operating systems side-by-side. If a user wanted the device to appear innocuous, they booted into normal Android. If they wanted to return to their sensitive chats, they switched over to the Encrochat system. The company sold the phones on a subscription based model, costing thousands of dollars a year per device.
This allowed them and others to investigate and arrest many:
Unbeknownst to Mark, or the tens of thousands of other alleged Encrochat users, their messages weren't really secure. French authorities had penetrated the Encrochat network, leveraged that access to install a technical tool in what appears to be a mass hacking operation, and had been quietly reading the users' communications for months. Investigators then shared those messages with agencies around Europe.
Only now is the astonishing scale of the operation coming into focus: It represents one of the largest law enforcement infiltrations of a communications network predominantly used by criminals ever, with Encrochat users spreading beyond Europe to the Middle East and elsewhere. French, Dutch, and other European agencies monitored and investigated "more than a hundred million encrypted messages" sent between Encrochat users in real time, leading to arrests in the UK, Norway, Sweden, France, and the Netherlands, a team of international law enforcement agencies announced Thursday.
EncroChat learned about the hack, but didn't know who was behind it.
Going into full-on emergency mode, Encrochat sent a message to its users informing them of the ongoing attack. The company also informed its SIM provider, Dutch telecommunications firm KPN, which then blocked connections to the malicious servers, the associate claimed. Encrochat cut its own SIM service; it had an update scheduled to push to the phones, but it couldn't guarantee whether that update itself wouldn't be carrying malware too. That, and maybe KPN was working with the authorities, Encrochat's statement suggested (KPN declined to comment). Shortly after Encrochat restored SIM service, KPN removed the firewall, allowing the hackers' servers to communicate with the phones once again. Encrochat was trapped.
Encrochat decided to shut itself down entirely.
Lots of details about the hack in the article. Well worth reading in full.
The UK National Crime Agency called it Operation Venetic: "46 arrests, and £54m criminal cash, 77 firearms and over two tonnes of drugs seized so far."
Citizen Lab has a new report on Dark Basin, a large hacking-for-hire company in India.
Dark Basin is a hack-for-hire group that has targeted thousands of individuals and hundreds of institutions on six continents. Targets include advocacy groups and journalists, elected and senior government officials, hedge funds, and multiple industries.
Dark Basin extensively targeted American nonprofits, including organisations working on a campaign called #ExxonKnew, which asserted that ExxonMobil hid information about climate change for decades.
We also identify Dark Basin as the group behind the phishing of organizations working on net neutrality advocacy, previously reported by the Electronic Frontier Foundation.
Citizen Lab has notified hundreds of targeted individuals and institutions and, where possible, provided them with assistance in tracking and identifying the campaign. At the request of several targets, Citizen Lab shared information about their targeting with the US Department of Justice (DOJ). We are in the process of notifying additional targets.
BellTroX InfoTech Services has assisted clients in spying on over 10,000 email accounts around the world, including accounts of politicians, investors, journalists and activists.
Remember Spectre and Meltdown? Back in early 2018, I wrote:
Spectre and Meltdown are pretty catastrophic vulnerabilities, but they only affect the confidentiality of data. Now that they -- and the research into the Intel ME vulnerability -- have shown researchers where to look, more is coming -- and what they'll find will be worse than either Spectre or Meltdown. There will be vulnerabilities that will allow attackers to manipulate or delete data across processes, potentially fatal in the computers controlling our cars or implanted medical devices. These will be similarly impossible to fix, and the only strategy will be to throw our devices away and buy new ones.
On Tuesday, two separate academic teams disclosed two new and distinctive exploits that pierce Intel's Software Guard eXtension, by far the most sensitive region of the company's processors.
The new SGX attacks are known as SGAxe and CrossTalk. Both break into the fortified CPU region using separate side-channel attacks, a class of hack that infers sensitive data by measuring timing differences, power consumption, electromagnetic radiation, sound, or other information from the systems that store it. The assumptions for both attacks are roughly the same. An attacker has already broken the security of the target machine through a software exploit or a malicious virtual machine that compromises the integrity of the system. While that's a tall bar, it's precisely the scenario that SGX is supposed to defend against.
